Step-by-step explanation:
a) explanation:





b) explanation:





c) explanation: we already have all the data from John's house to Sara's House.
John's House to Sara's House = John's House to School + Sara's House to School.
Sara's House to School (Question #1) = 34mi
John's House to School (Question #2) = 10mi
34(mi) + 10(mi) = 44(mi)

Answer:
yes u r right bro
Step-by-step explanation:
Answer:
9.49 units at an angle of 71.6° with the horizontal
Step-by-step explanation:
Magnitude: [x^2 + y^2]^(1/2)
(3^2 + 9^2)^(1/2)
(90)^(1/2) = 3root(10) = 9.49
Direction:
Angle with the horizontal: tan inverse (y/x)
tan inverse of (9/3)
tan inverse of 3 = 71.6°
